Description
Technical field
The present invention relates to a kind of manufacture method of wood-based plate, relate in particular to the mixed method of making wood-based plate of a kind of agricultural crop straw and timber.
Background technology
Wood-based plate is widely used in a lot of fields, and is progressively enlarged because of having good physical property and being easy to machining, Surface Machining and facing performance.Its main raw material(s) of the wood-based plate of Chu Shouing all is a timber in the market.Adopt single wood-base fibre and particle panel material to manufacture a product and cause huge timber waste, and the yielding and splitting of single timber plate, product result of use and life-span influenced.Raising along with scientific and technological progress and life of farmers level, stalk is not re-used as the daily fuel in rural area, explores the effective way of stalk comprehensive utilization, to alleviate the contradiction of the timber resources poorness that enlarges day by day, receive publicity day by day, artificial board of straw is exactly the effective way that solves this contradiction.Yet compare with wood-base fibre and particle panel material, the problem that the agricultural crop straw wood-based plate exists on production technology has: adopt conventional approach to carry out the material fragmentation or fiber separation causes the fiber pick-up rate low, poor morphology influences the physics characteristic of product; Be unfavorable for the material that glue together because the stalk surface contains more,, be difficult to obtain the bonding strength of being satisfied with so adopt traditional Lauxite or phenolic resin glue.
Summary of the invention
The objective of the invention is provides a kind of agricultural crop straw and mixed method of making wood-based plate of timber made by some embodiment.This manufacture method can avoid that agricultural crop straw wood-based plate fiber pick-up rate of problem on production technology is low, poor morphology and stalk surface are unfavorable for the problem of gluing together.
To achieve these goals, the present invention adopts following technical scheme, and the concrete steps of realization are:
Step 1: the wood raw material after processing evenly mixes with sending into the siccative storehouse through at least a agricultural crop straw of processing;
Step 2: mixed material is delivered to the glue mixer applying glue after metering together;
Step 3: the wood shavings after the applying glue are delivered to table, sandwich layer spreading machine, take on evenly smooth slab on the backing plate upper berth by spreading machine;
Step 4: slab carries out precompressed through the continous way preformer;
Step 5: be transported in the multi-daylight press hot-formingly after the precompressed, obtain hair plates;
Step 6: hair plates is delivered to the buck machine, and stays for some time in the buck machine;
Step 7: hair plates is sent in length and breadth the cutting edge edger and is cut apart, and forms wood-based plate.
Wherein, in the step 1, the agricultural crop straw process is specially:
Step 101: with chaffcutter, hog cut-out, broken agricultural crop straw raw material;
Step 102: the agricultural crop straw raw material separates through the foreign material that airflow separator will wherein mix;
Step 103: send into oscillating riddle after rotator type chip dryer drying material is screened, qualified material is delivered to table, sandwich layer feed bin through blower fan;
Step 104: through measuring transporter, belt conveyer scale and resin added control device metering and control table, sandwich layer inventory and resin added respectively.
Wherein, described step 2 is specially: mixed material is delivered to glue mixer after metering together, and glue mixer uses the carbimide adhesive, or the mixture of carbimide adhesive and urea-formaldehyde resin adhesive carries out the applying glue operation.
The present invention has the following advantages:
1, adopts agricultural crop straw and the mixed wood-based plate of making of timber, solved the problem of China's timber resource shortage effectively, and add the raw material mix that the part wood raw material can effectively improve wood-based plate, thereby improve the wood-based plate quality;
2, adopt single carbimide adhesive, do not contain the formaldehyde that has a strong impact on human body health, and have the better waterproof energy; Also can adopt isocyanate adhesive and urea-formaldehyde resin adhesive to use jointly, thereby can reduce the use amount of isocyanate adhesive, reduce production costs, and can reduce the content of formaldehyde of production board, and improve the intensity of gummed.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
